The Hamilton County Surveyor's office requires a permit for crossing, out-letting or working within the easement of a regulated drain. Regulated Drains in Hamilton County consist of subdivision drains, field tiles, or open ditches and creeks. Failing to obtain a permit for work done on these drains will constitute a violation from the Surveyor's Office. The Hamilton County standards and specifications as published by the Surveyor's Office must be met and approved prior to the beginning of the work.
For more information on regulated drains, fees and the permitting process, contact the Hamilton County Surveyor Plan Reviewer assigned to the area of the county the work is to be performed. View a map showing the Plan Review Areas (PDF) and the Plan Reviewer assigned to those areas.
